CORRECT DETAILED ANSWERS ALREADY A

REVISED
1. A 55-year-old male has swelling of the feet. Which of the following most likely
aided in the development of this swelling?
A. Increased ATP production
B. Chloride movement out of the cell
C. Decreased hydrostatic pressure
D. Sodium and water retention
Rationale: Sodium and water retention increases fluid volume and hydrostatic
pressure, contributing to edema formation. Reduced ATP (A) impairs sodium-
potassium pumps, which can contribute to cellular swelling, but edema is primarily
driven by increased vascular hydrostatic pressure or decreased oncotic pressure.
Chloride movement (B) is not a primary driver. Decreased hydrostatic pressure
(C) would reduce, not increase, edema.
2. A patient has a myocardial infarction (heart attack) leading to progressive cell
injury causing cell death with severe cell swelling and breakdown of organelles.
What term defines this process?
A. Adaptation
B. Calcification
C. Apoptosis
D. Necrosis
Rationale: Necrosis is pathologic cell death resulting from ischemia, characterized
by cell swelling, organelle breakdown, and inflammation. Apoptosis (C) is
programmed, neat, and does not cause inflammation. Adaptation (A) is a
reversible change, not death. Calcification (B) is a deposition process.

3. Which term describes the reduction in cell size as a result of decreased workload
or stimulus?
A. Hypertrophy
B. Metaplasia
C. Hyperplasia
D. Atrophy
Rationale: Atrophy is the reduction in cell size and function that occurs when cells
are not used or stimulated effectively, such as in disuse or denervation.
Hypertrophy (A) is an increase in cell size. Hyperplasia (C) is an increase in cell
number. Metaplasia (B) is the replacement of one cell type with another.
4. The lack of sufficient oxygen within cells is known as:
A. Hypoxia
B. Ischemia
C. Necrosis
D. Apoptosis
Rationale: Hypoxia refers to oxygen deficiency at the cellular level. Ischemia (B) is
reduced blood flow, which can lead to hypoxia but is not the same. Necrosis (C) is
cell death. Apoptosis (D) is programmed cell death.
5. A 24-year-old female presents with excessive menstrual bleeding. The physician
identified endometrial changes that are due to hormonal imbalances. These cellular
changes would be referred to as:
A. Dysplasia
B. Pathologic dysplasia
C. Hyperplasia
D. Pathologic hyperplasia
Rationale: Pathologic hyperplasia is an abnormal increase in cell number due to
hormonal imbalance or other pathologic stimuli, not due to a normal physiologic
need. This is distinct from normal menstrual cycle endometrial proliferation.
Dysplasia (A) involves deranged cellular growth, not just increased number.
6. A patient has a heart attack leading to progressive cell injury causing cell death
with severe cell swelling and breakdown of organelles. What term defines this
process?
A. Adaptation
B. Calcification
,Page 3 of 49
C. Apoptosis
D. Necrosis
Rationale: Necrosis is pathologic cell death from ischemia characterized by
swelling and inflammation. Apoptosis (C) is programmed cell death without
inflammation. Adaptation (A) is a reversible change. Calcification (B) is a
deposition process.
7. Which term describes the reduction in cell size as a result of decreased workload
or stimulus?
A. Hypertrophy
B. Metaplasia
C. Hyperplasia
D. Atrophy
Rationale: Atrophy occurs when cells shrink in size because they are not being
used or stimulated effectively. This adaptation allows the cell to survive under
conditions of reduced nutrient supply or workload. Hypertrophy (A) refers to an
increase in cell size. Hyperplasia (C) involves an increase in the number of cells.
Metaplasia (B) is the replacement of one cell type with another.
8. The lack of sufficient oxygen within cells is known as:
A. Hypoxia
B. Ischemia
C. Necrosis
D. Apoptosis
Rationale: Hypoxia is oxygen deficiency at the cellular level. Ischemia (B) is
reduced blood flow, which can cause hypoxia. Necrosis (C) is cell death. Apoptosis
(D) is programmed cell death.
9. A 75-year-old male presents with chest pain and shortness of breath. An EKG
indicates a myocardial infarction. Which of the following cellular changes would
be expected in the affected cardiac tissue?
A. Hypertrophy
B. Hyperplasia
C. Coagulative necrosis
D. Liquefactive necrosis
Rationale: Coagulative necrosis is characteristic of hypoxic injury in solid organs
such as the heart, kidneys, and liver. It results from protein denaturation, leading
, Page 4 of 49
to cell death with preservation of tissue architecture. Liquefactive necrosis (D)
occurs in the brain or with bacterial infections.
10. A patient with a chronic infection develops a necrotic lesion in the lung that
appears soft, cheese-like, and white. This type of necrosis is best described as:
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
Rationale: Caseous necrosis is a distinct form of necrosis typically associated with
tuberculosis and fungal infections. It produces a soft, cheese-like, friable necrotic
material that is a mixture of coagulative and liquefactive necrosis. Fat necrosis
(D) occurs in the breast or pancreas.
11. A patient presents with an autoimmune disorder in which the body produces
antibodies against its own DNA. This is characteristic of:
A. Rheumatoid arthritis
B. Systemic lupus erythematosus (SLE)
C. Multiple sclerosis
D. Type 1 diabetes mellitus
Rationale: Systemic lupus erythematosus is an autoimmune disorder characterized
by the production of autoantibodies against nuclear antigens, including double-
stranded DNA. These antibodies form immune complexes that deposit in tissues,
leading to inflammation and damage in multiple organ systems.
12. Which of the following is a cardinal sign of acute inflammation?
A. Pallor
B. Hypothermia
C. Edema
D. Paresthesia
Rationale: Edema or swelling is one of the five cardinal signs of inflammation
caused by increased vascular permeability. Other cardinal signs include heat,
redness, pain, and loss of function. Pallor (A) and hypothermia (B) are not typical.
Paresthesia (D) is not a cardinal sign.
13. What is the primary pathophysiology behind Type I hypersensitivity reactions?
A. IgG mediated cytotoxic response
B. T-cell mediated delayed reaction
